For example, when Nature announced the re-appointment of Dr. Weiler as NASA science mission director last year after NASA had been in existence for almost 50 years, I asked him to use his new position to find out if:

a.) Experimental evidence of an IRON SUN is "crackpot science", as NASA's Dr. David Hathaway told a UPI reporter http://tinyurl.com/qbbafr , or

b.) NASA's insistence on a HYDROGEN-FILLED SUN is evidence of long-standing incompetence in our space agency.

Dr. Weiler did not respond, although high profile warnings of global warming by former VP Al Gore and the UN"s IPCC had focused new public attention on the Sun - The ultimate source of heat for planet Earth.

The need for NASA to provide a direct answer to this question was explained in a paper just published in Energy and Environment 20 (2009) 131-144,
